Research on Mechanical Characteristic of a Self-Force-Amplifier Damper

Abstract

The vibration energy dissipation theory of a self-force-amplifier dry friction damper has been discussed detail in this paper. The research shows that the new dampers have traditional dampers’ merit and overcome their shortcoming which can only offer invariable friction. At the same time, they can be feedback controlled by the displacement signals of the controlled structure. So the ability of energy dissipation and vibration control effect of the new damper can be augmented.
